Based on the development and application of maintenance template in developed countries,and combining with reliability-centered maintenance( RCM) analysis results and maintenance experience data over the past ten years in domestic NPPs, the development process of maintenance template was presented for Chinese pressurized water reactor( PWR) NPP,and the application of maintenance template to maintenance program development and maintenance optimization combined with cases were demonstrated. A shortcut was provided for improving the efficiency of maintenance optimization in domestic PWR NPP,and help to realize a safe,reliable,and economic operation for domestic NPPs.展开更多

In the pilot project,the RCMbased maintenance decision methodology had been applied to determining the maintenance strategies for two systems. Both the decision process and the results were described in this paper. The achievements of this project promoted the introduction and routinization of an advanced and effective maintenance decision mode in nuclear power field,which could provide valuable reference for new NPPs in China.展开更多

Apart from the regular work required by the plant’s annual check- up plan, all of the present guide tubes of the control rods in Unit I will be replaced by the type of state-of-the-art tubes used in Unit 2, to make the dropping-time of the tubes more accurate. The annual check may take 80 days, thus the unit will probably re-connect with the power grid in mid June. As for Unit 2, the "exciter" of generator malfunctioned during the start of the reactor on March 6, when the second refueling and maintenance neared completion.展开更多
